New Accounting Pronouncements or Change in Accounting Principle [Line Items]
Basis of presentation and consolidation	Basis of Presentation and Consolidation. The Company's unaudited condensed consolidated financial statements are prepared on the accrual basis of accounting in accordance with GAAP. The financial statements reflect the accounts of the Company and its consolidated subsidiaries.
Variable interest entity	On January 1, 2016, the Company adopted Accounting Standards Update (“ASU”) 2015-02 (Topic 810), Amendments to the Consolidation Analysis, modifying the analysis it must perform to determine whether it should consolidate certain types of legal entities. The guidance does not amend the existing disclosure requirements for variable interest entities (“VIEs”) or voting interest model entities. The adoption of this guidance had no impact on consolidated entities included in the Company's unaudited consolidated financial statements as all entities previously consolidated are still consolidated and all entities previously not consolidated are still not consolidated. However, under the revised guidance, the Company determined that certain affiliated limited partnerships and similar entities are now considered, by definition, VIEs. These entities were determined to be VIEs as the unaffiliated partners/members did not have simple majority substantive kick-out rights or participating rights. The Company determined that it was the primary beneficiary of certain VIEs as it has a controlling financial interest in these entities. LCIF, which continues to be consolidated and in which the Company has an approximate 96% interest, was determined to be a VIE under this new guidance.
Use of estimates	Use of Estimates. Management has made a number of significant estimates and assumptions to prepare these unaudited condensed consolidated financial statements in conformity with GAAP, including, among others, those relating to the reporting of assets and liabilities, the disclosure of contingent assets and liabilities and the reported amounts of revenues and expenses. These estimates and assumptions are based on management's best estimates and judgment. Management evaluates its estimates and assumptions on an ongoing basis using historical experience and other factors. Management adjusts such estimates when facts and circumstances dictate. The most significant estimates made include the recoverability of accounts receivable, the allocation of property purchase price to tangible and intangible assets acquired and liabilities assumed, the determination of VIEs and which entities should be consolidated, the determination of impairment of long-lived assets, loans receivable and equity method investments, the valuation of derivative financial instruments, the valuation of compensation plans and the useful lives of long-lived assets. Actual results could differ materially from those estimates.
Fair value measurements	Fair Value Measurements. The Company follows the guidance in the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification Topic 820, Fair Value Measurements and Disclosures, as amended (“Topic 820”), to determine the fair value of financial and non-financial instruments. Topic 820 defines fair value, establishes a framework for measuring fair value in GAAP and expands disclosures about fair value measurements. Topic 820 establishes a fair value hierarchy that prioritizes observable and unobservable inputs used to measure fair value into three levels: Level 1 - quoted prices (unadjusted) in active markets that are accessible at the measurement date for assets or liabilities; Level 2 - observable prices that are based on inputs not quoted in active markets, but corroborated by market data; and Level 3 - unobservable inputs, which are used when little or no market data is available. The fair value hierarchy gives the highest priority to Level 1 inputs and the lowest priority to Level 3 inputs. In determining fair value, the Company utilizes valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible, as well as considering counterparty credit risk. The Company has formally elected to apply the portfolio exception within Topic 820 with respect to measuring counterparty risk for all of its derivative transactions subject to master netting arrangements.
Acquisition, development and construction arrangements	Acquisition, Development and Construction Arrangements. The Company evaluates loans receivable where the Company participates in residual profits through loan provisions or other contracts to ascertain whether the Company has the same risks and rewards as an owner or a joint venture partner. Where the Company concludes that such arrangements are more appropriately treated as an investment in real estate, the Company reflects such loan receivable as an equity investment in real estate under construction in the unaudited condensed consolidated balance sheets. In these cases, no interest income is recorded on the loan receivable and the Company capitalizes interest during the construction period. In arrangements where the Company engages a developer to construct a property or provides funds to a tenant to develop a property, the Company will capitalize the funds provided to the developer/tenant and internal costs of interest and real estate taxes, if applicable, during the construction period.
Reclassifications	Reclassifications. Certain amounts included in the 2015 unaudited condensed consolidated financial statements have been reclassified to conform to the 2016 presentation.
Recently issued accounting guidance	Recently Issued Accounting Guidance. In April 2014, the FASB issued ASU 2014-08, Presentation of Financial Statements (Topic 205) and Property, Plant and Equipment (Topic 360): Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity, which changes the criteria for reporting discontinued operations and improves financial statement disclosures. Under this guidance, only disposals representing a strategic shift in operations that have a major effect on an organization's operations and financial results should be presented as discontinued operations. The Company adopted this guidance effective January 1, 2015. The guidance requires the Company to continue to classify any property disposal or property classified as held for sale as of December 31, 2014 as discontinued operations prospectively. Therefore, the revenues and expenses related to these properties are presented as discontinued operations. The Company did not classify any additional properties as discontinued operations subsequent to December 31, 2014, as the dispositions did not represent a strategic shift in operations. The implementation of this guidance did not have a material impact on the Company's financial position, results of operations or cash flows. In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606), which amends the guidance for revenue recognition to eliminate the industry-specific revenue recognition guidance and replace it with a principle-based approach for determining revenue recognition. The effective date of the new guidance was updated by ASU 2015-14 and is effective for reporting periods beginning after December 15, 2017. Early adoption is permitted. The Company is currently evaluating the impact of the adoption of the new guidance on its consolidated financial statements. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842), which requires lessees to recognize a right of use asset and related lease liability for those leases classified as operating leases at the commencement date and have lease terms of more than 12 months. The accounting applied to lessors under this new guidance is largely unchanged from prior guidance. Lessors in most cases will continue to record operating leases as operating leases and recognize lease income from those leases generally on a straight-line basis over the lease term. ASU 2016-02 is effective for fiscal years beginning after December 15, 2018, and interim periods within those years, and requires a modified retrospective transition approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. Early adoption is permitted. The Company is currently evaluating the impact of the adoption of the new guidance on its consolidated financial statements. In March 2016, the FASB issued ASU 2016-09, Compensation-Stock Compensation-Improvements to Employee Share-Based Payment Accounting (Topic 718), which involves several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. This ASU is effective for fiscal years beginning after December 15, 2016, including interim periods within that reporting period, however early adoption is permitted. The Company is currently evaluating the impact of the adoption of the new guidance on its consolidated financial statements. In June 2016, the FASB issue ASU 2016-13, Financial Instruments - Credit Losses (Topic 326), which requires more timely recognition of credit losses associated with financial assets. The ASU is effective for fiscal years beginning after December 15, 2019, and for interim periods within those fiscal years. Early adoption is permitted for fiscal years beginning after December 15, 2018. The Company is currently evaluating the impact of the adoption of the new guidance on its consolidated financial statements.

Basis of presentation and consolidation	Basis of Presentation and Consolidation. The Partnership's unaudited condensed consolidated financial statements are prepared on the accrual basis of accounting in accordance with GAAP. The financial statements reflect the accounts of the Partnership and its consolidated subsidiaries. The Partnership consolidates its wholly-owned subsidiaries, partnerships and joint ventures which it controls (i) through voting rights or similar rights or (ii) by means other than voting rights if the Partnership is the primary beneficiary of a variable interest entity (“VIE”). Entities that the Partnership does not control and entities that are VIEs in which the Partnership is not the primary beneficiary are accounted for under appropriate GAAP.

Certain expenses incurred by the General Partner and its affiliates, including Lexington, such as corporate-level interest, amortization of deferred loan costs, payroll and general and administrative expenses are allocated to the Partnership and reimbursed to the General Partner in accordance with the Partnership's partnership agreement. The allocation is based upon gross rental revenues.
